FOOT-ACCELERATOR FOR FORD CARS.

Specification of Letters Patent.

Patented Jan. 25, 1921.

Application filed November 21, 1919. Serial No. 339,722.

To all whom it may concern Be it known that I, RUssnLL MARTIN, a citizen of the United States, residing at Honesdale, in the county of VVayneand Stateof Pennsylvania, have invehted certain new and useful Improvements in Foot- Accel'erators for Ford Cars, of which the following is a specification, reference being had to the accompanying drawings f This invention relates to accelerators, and particularly to means for accelerating Ford cars by an opening movement of the throttle valve.

In Ford cars the throttle valve is connected by a rod or wire to an arm rotatably mounted upon the steering column and connected to an operating arm mounted upon the steering wheel.

The general object of my invention is to provide pedal actuated means for control ling the opening movement of the throttle which will permit the controlling lever or arm on the steering wheel to be shifted to any desired running position and cause the throttle to be opened to a greater or less extentbut which will permit the further opening of the throttle to accelerate the car upon the depression of the foot actuated pedal.

A further object is to provide mechanism of this kind which is extremely simple, may be very cheaply made, and which may be applied to a Ford car with a minimum of trouble and with practically no alteration in the car.

Other objects will appear in the course of the following description.

My invention isillustrated in the accompanying drawings, wherein Figure 1 is a top plan view showing my invention applied;

Fig. 2 is a perspective view of the device;

Fig. 3 is av detail view of the foot pedal of the device.

Referring to these drawings, the carbureter of the car A is designated 10 and has the usual arm 11. A spring 12 engages at one end with the arm 11 and at the other end with the car body and normally holds the throttle valve of the carbureter closed. A wire, rod, or other equivalent connection 18 extends from the arm 11. There is mounted within the steering column of a Ford car a shaft which extends up through the steering column and at its upper end is connected to an actuating handle let moving over a rack. This shaft 15 at its lower end carries a radially extending arm 16 formed with an eye. So far, the parts described are those ordinarily found on Ford cars, the arm 16 being operatively connected to the wire or connection 13 so that when the shaft 15 is rotated by the handle 14 in one direction, the throttle valve will be opened and may be moved to its fully opened position, and that when the handle is moved in the opposite direction, the spring 11 will cause the closing of the throttle valve or its movement toward its closing position.

My attachment comprises a foot pedal 17 mounted upon a bracket 18, in turn mounted upon the inclined floor board 19 of the car A. This foot pedal projects from or is otherwise operatively connected to a rod 20. This rod at one end is provided with a pin 21 adapted to engage with the eye in the arm 16 and hold the rod 20 in engagement with said arm. This rod 20 is also provided with a radial arm 22 having means at its end for engagment with the eye in the wire 1.3. The rod 20 is in the nature of a shaft, being rotatable on its longitudinal axis and mounted in suitable bearing, and preferably the pedal 17 vis formed by bending the extremity of the rod 20 so as to form a crank arm on the rod. hen this crank arm is depressed, the rod 20 is rotated in a direction to cause the arm 22 to exert a pull on the wire 13 to thereby open the throttle valve or shift it toward its fully open position. This rotation of the rod 20, it will be obvious, will not affect the arm 16, but the rod 20 will merely rotate within the eye of the arm 16. lVhen, however, the shaft 15 is rotated, the arm 16 will exert a lateral pull on the forward end of the rod 20 and this lateral pull will be transmitted through arm 21 to wire 13 and so to the throttle valve arm 11. Of course, it will be obvious that the shaft 20 is loosely mounted in its bearing bracket 18 and passes loosely through the opening in the foot board 19 in order to permit the forward end of the shaft 20 to shift laterally when the manually operable 'carbureter controlling shaft 15 is operated.

It will be seen that with this construction, the handle 1% may be shifted to adjust the throttle valve in the usual manner, and

that then whenever desired the foot pedal the brake pedal,

- to be installed. 7

justed positions. In installing this device, all that is necessary is to bore a hole 23 in the floor board about 211 to the right of The rod 20 is then put through the hole and the bracket 18 fastened to. the floor board. The wirev 13 is then disconnected from the arm 16 and the shaft or rod 20 is connected to the arm 16. 'The wire'is then connected to the arm 22. Preferably, the arm 22 is loose on the rod or shaft 20, but has means whereby it may be rigidly fastened in any adjusted position thereon. It will be noted that with this construction no bolts are required to be removed from the engine, and practically no alteration has to be made in the car or any parts removed in order to permit my device I claim z- 7 1. In a motor driven vehicle, the combination with a throttle valve having an operat ing arm, a shaft having a handle and having a radial arm, a foot pedal operated shaft having one end engaged in said arm for rotationtherein or for movement therewith, said second named shaft having a radially extending arm, a connection between said 1 arm and the throttle valve arm, and a spring normally urging the throttle valve to a closed position.

2; In a motor car, the combination with a carbureter having an operating arm, a steering post, a shaft rotatably mounted in connectiontherewith and having an operat ing handle at one end and a radial arm, a shaft having at one end detachable connec tion with the radial arm and extending through the dash board of the machine and having acranked end forming a pedal, the

opposite end of the shaft being rotatably supported in and movable with the arm on the first named shaft, said second named shaft having a radially extending arm, a connection between this last named arm and the throttle valve arm, and a spring normally urging the throttle valve to a closed position. y

8. In a motor car, the combination with a throttle valve having a radially extending arm, a steering post,'a shaft mounted thereon and having a handle and a radial arm;

formed with an eye, a second shaft rotatably moiinted at one end in the foot board of the machine and formed at this end with a cranked'portion constituting a pedal, the

opposite end of the shaft being adapted to be inserted through thefleye' on'the arm of the first named shaft and rotatably supported in said eye, a bracket'supporting the pedal end of the second named shaft, a
